IRA A. SHANTON, OF ST. PETERSBURG, FLORIDA.

SPRING-MOTOR.

To all whom it may concern:

Be it known that I, IRA A. SHANTON, a citizen of the United States,residing at St. Petersburg, in the county of Hillsboro and State ofFlorida, have invented certain new and useful Improvements inSpring-Motors, of which the following is a specification.

This invention relates to spring motors designed more particularly foroperating fans, and one of the principal objects of the invention is toprovide an efficient, reliable anfd compact portable device foroscillating a an.

Another object of the invention is to provide a spring motor of simpleconstruction which can be manufactured at a low cost for oscillating afan, means being provided for regulating the speed of the fan, and meansbeing also provided for attaching the motor to a chair, desk, bed orother object, and to permit the fan to be adjusted in Va rious positionsfor use.

Still another object of the invention is to provide a spring motor foroperating fans comprising a casing having inolosed therein a pair ofmutilated gears actuated by coil springs, said gears adapted to be woundup by bevel gears and to alternately rotate in opposite directions tooscillate a fan, said fan being connected to a shaft provided with twosectors, one for each mutilated gear, and an escapement device forholding one of the gears against rotation, while the other is rotatedand vice versa.

These and other objects may' be attained by means of the constructionillustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of my invention complete. Fig. 2 is avertical section taken on the line 22 of Fig. 4 looking in the directionindicated by the arrow. Fig. 3 is a sectional view taken on the line 33of Fig. 4 looking in the direction indicated by the arrows. Fig. 4 is avertical sectional view taken at right angles to the View shown in Fig.3. Fig. 5 is a detail sectional View showing the brake for regulatingthe speed of the motor.

Referring to the drawings the numeral 1 designates a casing of therequired size and shape and containing the motor, said casing having,preferably, an enlargement 2 upon its upper side, said enlargement beingpro- Specification of Letters Patent.

vided with a slot 3. The casing 1 is provided with a suitable detachablecover plate 4. Connected to a socket 5 at the bottom of the casing is arod 6, said rod being provided with a collar 7 adapted to rest upon asleeve 8, through which the rod 6 extends. A ball-and-socket hinge 9 isprovided for the adjustment of the fan in any desired position. Asupporting rod 10 is connected to the balLand-socket hinge at one endand the other end is secured to a suitable hinge clamp 11 provided witha swinging eye bolt -12 for attaching the fan motor to a. chair,

desk, table, bed or other piece of furniture or support. J ournaled inthe opposite sides of the casing are stub shafts 13-14 and on the innerends of said shafts are beveled gears 15-16, said beveled gears beingoppositely disposed and constantly in mesh with a similar beveled gear17 mounted upon the inner end of the winding spindle 18 journaled in abracket 19 in the casing, and extending through a bearing 20 formed inone side of the casing, said spindle being provided with a squaredportion 21 to receive the Winding key. Secured to the stub shaft 13 is amutilated gear 22, said gear having a series of cogs 23 on the peripherythereof, said series of cogs being spaced apart by means of plainuncogged portions 24.

A series of stop pins 25 are secured to the inner side of the mutilatedgear 22 adjacent to the cogs 23. A clock spring 26 is secured at one endto the shaft 13, while the opposite end is secured to the inner wall ofthe casing 1. Upon the stub shaft 14 a mutilated gear 22 is secured,said gear being provided with cog teeth 23 substantially identical withthose already described. Stop pins 25 are secured to this mutilatedgear, said pins projecting inwardly. A clock spring 26 is secured to theshaft 14 at one end, while the opposite end is secured to the casing 1.The mutilated gears 22 and 22" are disposed in parallel relation and theplain portion 24 of the gear 22 is disposed in alinement with the cogteeth 23 on the gear 22 A shaft 27 is journaled in the enlargement 2 ofthe casing. Secured to this shaft are two toothed sectors 2829, saidsectors adapted to engage the cog teeth 2323 on the mutilated gears. Averge or escapement device 29 is connected to the sleeve 30 on which thesector 29 is formed, said escapement device having a curved rim 31,provided with project-ing ends 32, which engage the pins 25 at the endof each stroke of the shaft 27. A similar escapement 29 is formed on thesleeve 30* to engage the pins 25 on the mutilated gear 22 Securedcentrally to the shaft 27 is a sleeve 33 provided with a socket 34C inwhich is fitted a handle 35 on a fan 36. One end of the shaft 27projects through a bearing 37 formed on the cover plate 4, and a boss 38is formed on the bearing 37 to provide for a spring speed regulatingbrake 39, which bears upon the shaft to create friction to prevent therapid oscillation of said shaft. A spring 40 bears upon the brake and athumb screw tf is utilized for adjusting the brake.

The operation of my invention may be briefly described as follows: Afterthe springs have been wound by means of a key placed upon the squaredend 21 of the spindle 18, said springs being wound in oppositedirections by means of the beveled gears 15, 16, 17, the mutilated gear22 will rotate in the direction indicated by the arrow thereon, whilethe mutilated gear 22 will rotate in the opposite direction as indicatedby the arrow on this gear. At the end of each stroke of the fan, one ofthe mutilated gears is stopped by the projecting end 32 of theescapement device engaging one of the pins 25.

From the foregoing it will be obvious that a spring fan motor made inaccordance with my invention, can be manufactured at low cost, is simplein construction, is eflicient and reliable in operation, cannot readilyget out of order, can be quickly wound, can be ad j usted to suitvarious conditions or positions and that the speed of the motor may beregulated at will.

I claim:

1. A fan motor comprising a casing, stub shaft-s mounted in the casing,oppositely disposed beveled gears connected to said shafts on the insideof the casing, clock springs connected to said stub shafts and to saidcasing, a centrally disposed beveled gear adapted to mesh with the firstnamed beveled gears for winding the springs, mutilated gears connectedto said stub shafts and provided with cog teeth at intervals, sectorsmounted upon a separate shaft, escapement devices on said sectors and afan connected to said shaft for oscillation, substantially as described.

2. A spring motor comprising a casing, stub shafts mounted in thecasing, beveled gears oppositely disposed in said casing, a windingbeveled gear in mesh with said first mentioned beveled gears, springs onsaid stub shafts, mutilated gears on said stub shafts, a fan shaft,toothed sectors connected to said shaft, a fan connected to said shaft,and means for stopping one of the mutilated gears, while the other isrotated.

3. A spring motor comprising a casing, stub shafts in the casing,springs secured to said stub shafts and to said casing, means foroppositely rotating said stub shafts for winding up said springs,mutilated gears connected to said stub shafts, a fan shaft, toothedsectors connected to said fan shaft for meshing with the teeth on themutilated gears, escapement devices for holding one of the mutilatedgears, while the other is rotated, and vice versa.

In testimony whereof I affix my signature in presence of two witnesses.
